prepainted galvanized steel roofing coils
,PPGI construction panels with warranty
,PPGL steel coils for roofing
High-quality PPGI steel coil with excellent corrosion resistance and color durability. Ideal for roofing, wall panels, and appliances. Custom sizes & colors available. Factory direct supply.
PPGI steel coil (Prepainted Galvanized Steel Coil) is a high-value coated steel product manufactured by applying organic paint layers onto galvanized steel substrate. It combines the strength of steel with superior corrosion resistance and aesthetic flexibility, making it widely used in construction, home appliances, and industrial applications.
Our PPGI coils are produced using advanced coating lines, ensuring uniform paint thickness, strong adhesion, and long-term durability. With options such as PE, SMP, and PVDF coatings, customers can choose the most suitable solution based on environmental conditions and project requirements.

PPGI stands for Prepainted Galvanized Iron. It is a coated steel product made by painting galvanized steel, offering both corrosion protection and decorative appearance.
PPGI uses galvanized steel (zinc coating), while PPGL uses galvalume steel (aluminum-zinc coating). PPGL generally provides better corrosion resistance, while PPGI is more cost-effective.
The lifespan depends on the coating type and environment:
- PE: 8–10 years
- SMP: 10–15 years
- PVDF: 20+ years
Yes, we offer full customization including:
- RAL color matching
- Thickness & width
- Coating thickness
- Surface finish
Yes, PPGI is widely used for roofing sheets due to its durability, corrosion resistance, and aesthetic appearance.
